Member Function Documentation

◆ as()

template<typename T >

std::shared_ptr<T> fable::schema::Box::as ( ) const

inline

Return this type as a pointer to T.

This method can be used like so:

// In this example, we want a Struct.
auto ptr = s.template as<Struct>();

Here is the call graph for this function:

◆ as_unsafe()

template<typename T >

std::shared_ptr<T> fable::schema::Box::as_unsafe ( ) const

inline

Return this type as a pointer to T.

This is unsafe in that you need to check the resulting shared pointer yourself for whether the dynamic cast was successful or not.

Here is the call graph for this function:

◆ clone()

Interface* fable::schema::Box::clone ( ) const

inlineoverridevirtual

Return a new instance of the object.

This is implemented by Base and allows us to wrap implementors of Interface with Schema.

Implements fable::schema::Interface.

Here is the call graph for this function:

◆ description()

const std::string& fable::schema::Box::description ( ) const

inlineoverridevirtual

Return human-readable description.

Implements fable::schema::Interface.

◆ from_conf()

void fable::schema::Box::from_conf ( const Conf & )

inlineoverridevirtual

Apply the input JSON configuration.

This does not validate the input.

Implements fable::schema::Interface.

◆ get()

std::shared_ptr<Interface> fable::schema::Box::get ( )

inline

Return the underlying Interface.

◆ is_required()

bool fable::schema::Box::is_required ( ) const

inlineoverridevirtual

Return whether this interface needs to be set.

Implements fable::schema::Interface.

◆ json_schema()

Json fable::schema::Box::json_schema ( ) const

inlineoverridevirtual

Return the JSON schema.

Example output:

{ "$schema": "http://json-schema.org/draft-07/schema#", "description": "stand-in no-operation simulator", "properties": { "vehicles": { "description": "list of vehicle names to make available", "items": { "type": "string" }, "type": "array" } }, "title": "nop", "additionalProperties": false, "type": "object" }

See the following links for the specification:

Implements fable::schema::Interface.

Here is the caller graph for this function:

◆ reset_ptr()

void fable::schema::Box::reset_ptr ( )

inlineoverridevirtual

Reset the internal pointer to nullptr, protecting against invalid access.

This should be used when a schema is used after the backing data has been deleted.

Implements fable::schema::Interface.

Here is the call graph for this function:

◆ set_description()

void fable::schema::Box::set_description ( const std::string & s )

inlineoverridevirtual

Set human-readable description.

Implements fable::schema::Interface.

◆ to_json()

void fable::schema::Box::to_json ( Json & ) const

inlineoverridevirtual

Return the current value of the destination.

Warning: This is NOT an efficient operation, but it can be useful for cases where speed is not important.

Implements fable::schema::Interface.

◆ type()

JsonType fable::schema::Box::type ( ) const

inlineoverridevirtual

Return the JSON type.

If this is a variant type of differing types, then null should be returned. Otherwise, the type remains unique and can be returned. A type that is null is almost always a variant type of some sort, if even only an optional type.

Implements fable::schema::Interface.

◆ type_string()

std::string fable::schema::Box::type_string ( ) const

inlineoverridevirtual

Return the type as a string.

The format of the string is:

"[array of] TYPE"

where TYPE is one of: null, object, boolean, float, integer, unsigned, string, and unknown.

Example output:

"object"
"array of boolean"
"array of object"

Implements fable::schema::Interface.

◆ usage()

Json fable::schema::Box::usage ( ) const

inlineoverridevirtual

Return a compact JSON description of the schema. This is useful for human-readable error output.

Example output:

{ "field1": "boolean! :: lorem ipsum dolor sit amet", "field2": { "field2.1": "integer :: lorem ipsum dolor sit amet" "field2.2": "boolean :: lorem ipsum dolor sit amet" }, "field3": "array of integer :: lorem ipsum dolor sit amet", "field4": [{ "field4.1": "string :: lorem ipsum dolor sit amet" "field4.2": "boolean :: lorem ipsum dolor sit amet" }] }

When describing the schema of a primitive array, we can represent that as a single string. But when the array contains an object, we wrap a single object in an array. This isn't awfully consistent, but it's the best we can do.

Implements fable::schema::Interface.

◆ validate()

void fable::schema::Box::validate ( const Conf & c ) const

inlineoverridevirtual

Validate the input JSON configuration.

If you don't have a Conf but would like to validate a Json type, then construct a Conf on the fly:

s.validate(Conf{j});

This function is not provided inline to prevent incorrect use.

Implements fable::schema::Interface.
